How to display tictactoe board using map and forEach? : <p>I want to display tic tac toe board. Something like that:</p>
<pre><code>XXX
XXX
XXX
</code></pre>
<p>Is it possible to use for each to achieve that?
I tried to do some:</p>
<pre><code> Map<Integer, Tile> board = generateBoard();
for (Map.Entry<Integer, Tile> entry: board.entrySet()){
System.out.print(entry.getValue().getSign());
}
board.forEach((k,v) -> {
int i = 1;
if(i % 3 == 0){
System.out.println();
}
System.out.print(v.getSign());
i++;
});
</code></pre>
<p>But my output is incorrect. Could you give me any output to achieve me this output?</p>

In Java, how can I convert a string to a double (not Double)? : <p>It's part of a school lab and I've researched and I can't find anything to accomplish this task. I'm reading in lines from a file using FileReader and BufferedReader. The data in the file is a name and an age in the following format:</p>
<p>John doe 20 </p>
<p>Jane doe 30</p>
<p>etc. I already have code that will take each line and split as such:
split[0] = {"John", "doe", "20"}</p>
<p>I need to get the "20" and store in an array of doubles such as double[0] = 20;</p>
<p>The reason it has to be a double and not Double is because that part of the code in the assignment is already written and I'm sure I cannot just decide to change everything and use a Double instead. How can I do this? Thank you in advance!</p>

Change class on first element with Jquery : <p>I have a certain amount of <code>divs</code> inside another <code>div</code>, I need to change the first child class.</p>
<pre><code><div class="parent">
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
</div>
</code></pre>
<p>The idea is to change to <code>item</code> active the first item</p>
<p>I tried:</p>
<pre><code>$("parent").first("item").removeclass("item").addclass("item active");
</code></pre>
<p>but is not working</p>

Why is angular.io using old version of Angular? : <p>If I read the source of <a href="https://angular.io/" rel="nofollow noreferrer">https://angular.io/</a> right, it looks to me that they are still using Angular 1 there i.e. 1.6 version. To me it is a hint that while the new version of Angular is very advanced there are still challenges when it comes to production deployments of sites that are publicly available?</p>

Should I use a macro or a variable? : <p>I am rewriting a function and I noticed one particular variable is never reassigned after initialization. Is there any reason NOT to simply convert this variable to a macro? Is a macro ALWAYS preferable in this case?</p>

Is function(){}() valid? : <p>In a Javascript programming community, someone asked "How to declare anonymous method and run it immediately?" then others answered <code>(function(){})()</code> and <code>(function(){}())</code>.<br>
People who answered <code>(function(){}())</code> says that is correct and it's possible to run, but ideone says that is wrong and I think that is incorrect.<br>
Following links are for comparison between SpiderMonkey and Rhino.<br>

Webview loadurl issue : I had created one activity along with webview and loaded some url in it.But when i loaded google url in webview it opens in device browser but when i loaded some other urls in it,it works fine for me.
Permission added in manifest -
For ex -
This is open in device browser
WebSettings webSettings = webVw.getSettings(); webSettings.setJavaScriptEnabled(true); webVw.loadUrl("http://www.google.com");
This is opens in webview -
webVw = (WebView)findViewById(R.id.webVw); WebSettings webSettings = webVw.getSettings(); webSettings.setJavaScriptEnabled(true); webVw.loadUrl("https://stackoverflow.com");
Why this happens?Is there any other workaround to do it?

Add extra properties in Custom Exception to return to AJAX function : <p>I have a custom exception class as follows:</p>
<pre><code><Serializable>
Public Class SamException
Inherits Exception
Public Sub New()
' Add other code for custom properties here.
End Sub
Public Property OfferBugSend As Boolean = True
Public Sub New(ByVal message As String)
MyBase.New(message)
' Add other code for custom properties here.
End Sub
Public Sub New(ByVal message As String, ByVal inner As Exception)
MyBase.New(message, inner)
' Add other code for custom properties here.
End Sub
End Class
</code></pre>
<p>I'm using this for certain cases in returns from AJAX responses.</p>
<p>In the error function of my AJAX response I am determining that the error is of my custom type like this:</p>
<pre><code>....
ajax code....
.error = function (xhr, text, message) {
var parsed = JSON.parse(xhr.responseText);
var isSamCustomError = (parsed.ExceptionType).toLowerCase().indexOf('samexception') >= 0;
.... etc....
</code></pre>
<p>This allows me to post back a specific response to the client if the error is of my custom type.</p>
<p>BUT... I can't seem to get it to post out the extra property <code>OfferBugSend</code> to the client for the AJAX code to handle this case differently.</p>
<pre><code>console.log("OfferBugSend: " + parsed.OfferBugSend)
</code></pre>
<p>is showing undefined, and if I check the response, this is because <code>xhr.responseText</code> only contains the properties:</p>
<pre><code>ExceptionType
Message
StackTrace
</code></pre>
<p>These properties are from the base class <code>Exception</code> but it is not passing my custom class properties...</p>
<p>How can I make that happen?</p>

Translating HTML/JS/CSS to Ruby on Rails : <p>At the moment I have created a webpage that makes use of HTML, CSS, and Javascript but I need to implement ruby on rails next in order to do back end stuff as well as it's what my boss told me to utilize. Now I have never utilized Ruby on Rails so any guidance will be greatly appreciated. </p>
<p>Now I know that CSS has pre-processors such as SASS and others but how exactly do I utilize these. I also understand the basic structure of Rails in that there are different controllers and each one corresponds to different things. </p>
<p>Basically I would just like some guidance on how to implement a Ruby on Rails framework.</p>
<p>If you need any other information, I would be glad to oblige you with it. </p>

How to speed up these R computations? : <p>I have to data frames with X, Y, and Z coordinates. I want to find the distance between all of the points in the two data frames. (Like the distance between entry A1 and every entry in B, A2 and every entry in B, and so on, and vice versa). I basically did this:</p>
<p>1.) Wrote a function that calculates the distance between two points.
2.) Used the distanceFinder function to create a function that finds the distance between one point in a group, and every other point in the opposite group.
3.) Created a function called bigDistance() that calls filter() on every entry in one group, and appends the results to an empty data frame through a for loop until it's completed.</p>
<p>This code takes about 2 minutes to run on the file I'm experimenting with, and I just found out that I have to translate this algorithm to PHP... so I guess this is kind of an optimization question, because I feel like PHP would be way slower at making these computations than R? Sorry if people find this "off-topic" but yeah, super new to programming and Big O notation and stuff, so any tips would be amazing! Thanks!</p>

<p>And inside <code>c.py</code> I have the following:</p>

<p>Now I receive the following error:</p>
<blockquote>
<p>ValueError: attempted relative import beyond top-level package</p>
</blockquote>
<p>But <strong>why</strong>? How can I solve it? I am running <code>c.py</code> from the IDLE, and <code>pkg</code> should be considered a package, since it has the <code>__init__.py</code> file.</p>
<p>The first import works fine, but it's the following that doesn't work:</p>
<pre><code>from .. import d
</code></pre>
<p>Because I am attempting to import something from a parent package, but apparently I cannot, for some weird reason.</p>

How to daily rotate logs using Winston except the first day : <p>I need to rotate the logs daily except the file for current day.
I'm using <strong>winston</strong> and <strong>winston-daily-rotate-file</strong> libraries.</p>
<p>In the following example, a file "info.log.2016-08-09" is generated just the first time I execute node.</p>
<p>But, I really need to generate the file "info.log", and after this day, should be renamed to "info.log.2016-08-09", and create a new "info.log" for the current day.
I understant that this is the normal behaviour in other applications.</p>

Removing specific thing from multiple FOLDER names : <p>I'm trying to get info on trying to remove a specific thing from multiple folder names.. Preferably in such a way that it can be in a batch file.</p>
<p>For example.</p>
<p>Before:</p>
<pre><code>Test1 [REMOVEME]
Test2 [REMOVEME]
Test3 [REMOVEME]
Test4 [REMOVEME]
</code></pre>
<p>After:</p>
<pre><code>Test1
Test2
Test3
Test4
</code></pre>
<p>I've seen plenty of info about how to do this with files. But not folders. Is this doable with a batch file so it could be easily used later? Or will i need to use third party software?</p>
<p>Also. Am using Windows 10.</p>
<p>Thanks, Ben.</p>

How to set mode to development or production in the config file? : <p>We are migrating to webpack 4. We do have dev / prod config files already. We started getting this warning message:</p>
<pre><code>WARNING in configuration
The 'mode' option has not been set. Set 'mode' option to 'development'
or 'production' to enable defaults for this environment.
</code></pre>
<p>We can get around this by passing --mode production in the cmdline like below:</p>
<pre><code>npm run webpack --mode development ...
</code></pre>
<p>As is mentioned on the webpack documentation, blog and everywhere else on the internet. How can we set the config in the config file? Simply putting a mode: development under modules won't work. Just a bit frustrated why the documentation is just missing...</p>

Join table between Different Microservices : <p>I am still trying to make sense of micro service architecture.</p>
<p>The idea to separate different application (include the database) excites me. But I am still confused if there are two micro-services e.g. Product and User. both product and user own table product and user respectively in their database. According to best practice in micro service, we only can access the database from the service. </p>
<p>The problem is, let us suppose we have product table that has user_id column. We want to do search product which also return the name of the user who create the product. This requires join between product table in product micro-service and user table in user micro-service. How do you handle this? </p>

Do not understand how loop is determining how many asterix to print : I am a beginner at learning Java. I have stumbled upon a problem that I can not figure out. How is the loop in the code determining how many asterisk to print out. I keep looking at this part of the code..
asterisk < myArray[counter]
Could someone please explain in the simplest of terms how this works, because every time i think of the counter, i see it as nothing but the index that it is pointing to at that time in the loop. Thank you in advance. Full code below..
public class Main {
public static void main(String[] args) {
int[] myArray = {12, 7, 9, 11, 23};
System.out.println("Value Distribution");
//Start of outer for loop
for( int counter = 0; counter < myArray.length; counter++){
//Start of inner for loop
for( int asterisk = 0; asterisk < myArray[counter]; asterisk++)
System.out.print("*");
System.out.println();
}//End of outer for loop

basic pyodbc bulk insert : <p>In a python script, I need to run a query on one datasource and insert each row from that query into a table on a different datasource. I'd normally do this with a single insert/select statement with a tsql linked server join but I don't have a linked server connection to this particular datasource.</p>
<p>I'm having trouble finding a simple pyodbc example of this. Here's how I'd do it but I'm guessing executing an insert statement inside a loop is pretty slow.</p>
<pre><code>result = ds1Cursor.execute(selectSql)
for row in result:
insertSql = "insert into TableName (Col1, Col2, Col3) values (?, ?, ?)"
ds2Cursor.execute(insertSql, row[0], row[1], row[2])
ds2Cursor.commit()
</code></pre>
<p>Is there a better bulk way to insert records with pyodbc? Or is this a relatively efficient way to do this anyways. I'm using SqlServer 2012, and the latest pyodbc and python versions.</p>

how does cuda handle precisely a memory access : i would like to know how CUDA hardware/run-time system handles the following case.
If a warp(warp1 in the following) instruction involves access to the memory (load/store); the run-time system schedules the next ready warp for execution.
When the new warp is executed,
1- will warp1 "memory access" be conducted?
2- Will warp1 be put into a memory access waiting queue; once this operation is completed, the warp is then moved into the runnable queue?
3- will the Instruction pointer be incremented automatically to annotate that the memory access is done?
I hope my questions are clear.
Thank you

Google Fabric in Xcode 10 beta : <p>I installed Xcode 10 Beta 6 and I am updating everything and in this process I have run into a small issue with Fabric. Fabric's website has special instructions for Xcode 10 that says:</p>
<p><a href="https://i.stack.imgur.com/9Y5aN.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/9Y5aN.jpg" alt="Xcode 10 Instructions"></a></p>
<p>When I am in Xcode 10 I go to Build Phases an on the Run Script that has my Fabric key there is a + sign under the section <code>Input Fields</code></p>
<p>When I click the + it automatically generates <code>$(SRCROOT)/newInputFile</code> where <code>newInputFile</code> is automatically highlighted.</p>
<p>I'm not understanding Fabric's instructions. Do I copy the <code>$(BUILT_PRODUCTS_DIR)/$(INFOPLIST_PATH)</code> after <code>$(SRCROOT)/</code> Do I replace INFOPLIST_PATH with the file path to my info.plist?</p>
<p>I've tried all these options but Fabric is still crashing in Xcode 10. I know it is Fabric because I've commented out <code>Fabric.with([Crashlytics.self])</code> in my App Delegate's <code>didFinishLaunchingWithOptions</code></p>

Recommendable UI framework for phonegap? : <p>Before posting my question here I have looked across many posts but nothing relevant found. I'm developing an application for both Iphone and Andriod using Phonegap.</p>
<p>I came across with several UI related frameworks :</p>
<p>1.Framework 7
2.Ionic
3.Twitter Bootstrap
4.jQuery Mobile
5.Materializecss
6.jQuery UI
7.Sencha Touch</p>
<p>What is the recommended way of doing this? Meaning-designing a generic UI (tabbars, tables, navigation bars etc') for both Iphone,Android that will give the generic look and feel native?</p>
<p>I need to include Push notification, Camera access, local storage and RSS Feed as a functionality in my application.</p>
<p>Any leads will be appreciated and will be thankful to the core.</p>

git: why can't I delete my branch after a squash merge? : <p>I have a git repo with <code>mainline</code> (equivalent to <code>master</code>) and some local feature branches. For example:</p>
<pre><code>$ git branch
* mainline
feature1
feature2
feature3
</code></pre>
<p>When I do the following, I am able to squash merge all of my edits in a feature branch into one commit to <code>mainline</code>:</p>
<pre><code>$ git checkout mainline
$ git pull
$ git checkout feature1
$ git rebase mainline
$ git checkout mainline
$ git merge --squash feature1
$ git commit
$ git push
</code></pre>
<p>My question is, at this point, when I try to delete the <code>feature1</code> branch, it tells me it is not fully merged:</p>
<pre><code>$ git branch -d feature1
error: The branch 'feature1' is not fully merged.
If you are sure you want to delete it, run 'git branch -D feature1'.
</code></pre>
<p>What causes this error? I thought <code>git merge --squash feature1</code> merged <code>feature1</code> into <code>mainline</code>.</p>

web 2.0 sucks huge floppy disks? : <p>I was able to create a web site 10 years ago with Microsoft Frontpage without learning anything, today with a copy of Adobe Dreamweaver CS6, I can't even figure out a way to change the font size of a simple text. CSS is the thing, so I went through the CSS tutorials in w3 and I get it now. It's a good idea, but It is also a good idea to kill creativity, ie all sites like similar, see screenshot below. It sucks floppy disks.</p>
<p><a href="https://i.stack.imgur.com/AZO2h.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/AZO2h.jpg" alt="enter image description here"></a></p>
<p>My questions will be:</p>
<ol>
<li><p>Does web 2.0 really kill creativity?</p></li>
<li><p>Is there a "modern" web design application that I don't need to go into these CSS thing?</p></li>
<li><p>Is there a way to create a circular navigation menu like this using css? I want to have this menu in the middle of the page, and with a button on the corner to activate it.</p></li>

Editing a .csv file with a batch file : <p>this is my first question on here. I work as a meteorologist and have some coding experience, though it is far from professionally taught. Basically what I have is a .csv file from a weather station that is giving me data that is too detailed. (65.66 degrees and similar values) What I want to do is automate a way via a script file that would access the .csv file and get rid of values that were too detailed. (Take a temp from 65.66 to 66 (rounding up for anything above .5 and down for below) or for a pressure (29.8889) and making it (29.89) using the same rounding rules.) Is this possible to be done? If so how should I go about it. Again keep in mind that my coding skills for batch files are not the strongest. </p>
<p>Any help would be much appreciated. </p>
<p>Thanks,</p>

C++ Beginner - While loop repeating first iteration : <p>All,</p>
<p>So I've been really racking my brain about this one. I have a section of my program that needs to count spaces/vowels/characters in a user-specified string. This is one of those "teach you the way no one would do it because you can only used what we've covered in class already" kinds of assignments. So I have the user input a text, ending with a sentinel char, which in this case is '#'. The loop works wonderfully in regards to exiting when the sentinel is encountered, but it keeps iterating twice over string[0]. Here's the code: </p>
<pre><code>i = 0;
characterToBeProcessed = userInputText.at(i);
while (characterToBeProcessed != LOOP_SENTINEL)
{
fout << characterToBeProcessed;
// Convert to lowercase
characterToBeProcessed =
static_cast<char> (tolower(characterToBeProcessed));
// Increment character counters
switch (characterToBeProcessed)
{
case 'a':
case 'e':
case 'i':
case 'o':
case 'u':
totalVowelCount++;
totalCharacterCount++;
break;
case ' ':
totalSpaceCount++;
totalCharacterCount++;
break;
default:
totalCharacterCount++;
break;
}
characterToBeProcessed = userInputText.at(i++);
}
</code></pre>
<p>So when I input at the prompt: </p>
<pre><code>"Please input a text to be analyzed, ending with the # character: "
Hi there, my friend!#
</code></pre>
<p>The output is: </p>
<pre><code>Below is the text entered by the user:
HHi there, my friend!
Total characters: 21
Total vowels: 5
Total blank spaces: 3
</code></pre>
<p>I've had the program output the chars for .at(0) and .at(1), and those give me the correct characters, I just can't figure out why the loop iterates twice for the first char and then works fine after that second time through. The counts/output are otherwise correct except for the first char being duplicated. Any appreciation would be greatly appreciated. </p>
